Arteries
Arteries are elastic vessels that transport blood away from the heart. Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells. Systemic arteries deliver blood to the rest of the body.
Veins
Veins are elastic vessels that transport blood to the heart. Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins.
Capillaries
Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. Fluid and gas exchange between capillaries and body tissues takes place at capillary beds.
Sinusoids
Sinusoids are extremely small vessels located within the liver, spleen, and bone marrow.
Arterioles
a small diameter blood vessel that branches out from an artery to a capillary
Which of the following relationships between a tissue and its general function is not correct?
a) Epithelial : digestion
b) Connective ; support
c) Muscle ; movement
d) Nervous : control
Answer:
A) Epithelial
Explanation:
There are different kind of epithelial tissues, and depending on its clasification it could have different functions. For example the connective tissue has simple squamous epithelium. The digestive tract has a columnar epithelium. So the epithelial tissue has different functions: protection, regulation a secretion and those functions could help or improve the function of the different systems.
The incorrect relationship between a tissue and its general function is a) Epithelial : digestion. Epithelial tissue's primary functions include protection, absorption, secretion, and sensation detection, not digestion.
The relationship between a tissue and its general function that is not correct is: a) Epithelial : digestion. Epithelial tissue primarily covers and lines the body's surfaces, internal cavities, and passageways, and it forms certain glands. It has key roles in protection, absorption, secretion, and sensation detection but not directly in digestion. Connective tissue is known for providing support to the body and holding tissues together. Muscle tissue is involved in body movement through its ability to contract. Finally, nervous tissue controls the body by transmitting electrical signals through nerve impulses, allowing communication between different body regions. Looking back at the question's options, the function of digestion is not a primary function of epithelial tissue; therefore, option a) is the incorrect relationship between a tissue and its function.
The pulse pressure is _____
a. systoic pressure plus diastolic pressure
b. systoic pressure minus diastolic pressure
c. systolic pressure divided by diastolic pressure
d. diastolic pressure plus 1/3 (systolic pressure plus dastolic pressure)
Answer:
The answer is B: systoic pressure minus diastolic pressure
Explanation:
Pulse pressure is the difference between systolic blood pressure minus diastolic blood pressure and is a characteristic sign of arterial elasticity. Pulse pressure and wave morphology indicate the elasticity of the arteries.
Pulse pressure is calculated as the difference between systolic pressure and diastolic pressure, which provides insight into the health of an individual's arteries.
Explanation:The correct answer is option B which is the pulse pressure is the systolic pressure minus the diastolic pressure. When you measure your blood pressure, it involves two measurements: systolic blood pressure (the higher number and the first one that is mentioned) and diastolic blood pressure (the lower number and second one). The pulse pressure is the difference between these two numbers which provides information about the health of your arteries.

What major artery feeds into the kidneys?
Answer:
Renal Artery
Explanation:
It arises off the left interior side of the abdominal aorta.
Final answer:
The major artery that feeds into the kidneys is the renal artery, which branches from the aorta and supplies the kidneys with blood through a network of smaller arteries and arterioles.
Explanation:
The major artery that feeds into the kidneys is the renal artery. The renal arteries branch directly from the aorta, the largest artery in the body, entering the kidneys to supply them with blood. Each kidney receives around 10% of the total cardiac output, despite being relatively small organs.
Once they enter the kidneys, the renal arteries divide into several segmental arteries, which further branch into interlobar arteries. These give rise to arcuate arteries and then into cortical radiate arteries, which finally branch into numerous afferent arterioles that enter the capillaries supplying the nephrons. The nephrons are the functional units of the kidneys where the filtration of blood occurs.

When an enzyme catalyzes a reaction:
a. Substrate(s) bind in the active site
b. Products bind in the active site
c. The shape of the enzyme remains unchanged
d. The enzyme is consumed by the reaction
In an enzyme-catalyzed reaction, substrates bind in the enzyme's active site and enzymes are not consumed by the reaction. The shape of the enzyme undergoes slight changes during the reaction, but products do not bind in the active site. Instead, they are released once the reaction is complete.
Explanation:When an enzyme catalyzes a reaction, substrates indeed bind in the active site (a). This is because the active site is a unique part of the enzyme that has a specific shape and chemistry for binding substrates and catalyzing their conversion to products. However, products do not typically bind in the active site (b), they are usually released once the reaction is complete. In terms of the enzyme's shape (c), it is generally thought to be flexible and undergoes a slight change during the catalytic cycle, this is known as the "induced fit" model. Finally, the enzyme is not consumed in the reaction (d). Although it participates in the reaction, it does not permanently change or consumed, meaning that it can catalyze the same reaction many times over.

In enzyme-catalyzed reactions, substrates bind in the active site, the enzyme's shape can change, and the enzyme is not consumed by the reaction.
Explanation:When an enzyme catalyzes a reaction, the substrate(s) indeed bind in the active site (option a). This is because the active site of an enzyme is the specific region where the substrate interacts and where the catalysis of the reaction occurs. Option b is incorrect since products typically do not bind in the active site – they are released once the reaction is complete. As for option c, this is also incorrect because the shape of the enzyme can slightly change in a process known as induced fit to aid in catalysis. Lastly, option d is incorrect because, in general, the enzyme is not consumed by the reaction. Instead, it can be used repeatedly to catalyze the same reaction with other substrate molecules.
